UNITED (STATES PATENT OFFICE- i f A HENRY M. PREACHER, or BRUNSON, scorn CAROLINA.

' AERIAL RAILWAY. I

To all whom it may concern 1 Be it known that I, HENRY M. PREACHER,

a citizen of the United States, residing at Brunson, in the county of Hampton and State of South Carolina, have invented new ,1 and useful Improvements in Aerial Railways, of which the following is a specification.

This invention relates to aerial railways and the principal object of the invention is the provision of asimple and efiicient de-' vice of this character which may be cheaply constructed and installed and which. s

'especially designed for the transportation I of linemen from one point to another where the lines do not follow the road and which enablesthemto conveniently locate any'rupture of the lines and repair the same withf out climbing the poles or crawling among the messenger wires in hand propelled cars.

- Further objects of this inventionwill appear as the following specificdescription is.

' read in connection with the accompanying drawing, which forms a part of this application, and in which I I Figure 1 is a perspective view on a small scale. Fig. 2 is a vertical sectional view through the car on an enlargedscale. Fig.

' 3is a section on an enlarged scale taken'on the line 3-3 of Fig.2.

Referring more particularly to the drawing, 1 represents an ordinarytelegraph pole to which is secured a cross arm-2 braced in the usual manner by diagonal struts 3. iDelpending from the cross arm is a supportlar to that illustrated in Fig. 1. I This type of structure is'extremely 'oldin the art and needs no further description. Suspended from and adapted to travel over the wire is a car 6 which is supported in yoke members 7 whose upper ends have bearings 8 mounted therein to receivev the shafts 9. The

forward leg of each yoke member is inwardly curved, as shown at.10, so as to bring the cable pulleys 11 which arecon- I a nected to the shaft 9 immediately above the center of the car, whereby the same will I 'pcsite ends of the shaft from that to which. I the pulleys are secured have attached therehang perpendicularly" at all times. I The 'op- Specification of Letters Patent.

to suitable sprocket wheels 12 over which travels a sprocket chain 13 passing at its Patented Dec.17,1912. l Application filed May 1,1912. Serial no. 694,345.

ply is obtained from the tank 17. Interme-,

diate the engine and the sprocket wheel 14, the shaft 15 has secured thereto a pair 'of friction members 18 adapted to mesh or en'- gage with cups or concave disks 19 keyed to the shaft and carrying beveled gears 20' which meshwith similar gears 21 mounted in the casing 22. The friction members 18 are carried by the sleeve 23 which is splined upon the shaft and provided with'a central collar 24 adapted to be engagedby the shifting lever25. This reverse mechanism is provided so that the engine can be connecte ed todrive the shaft 15 in either direction, it being of course understood that the shaft is in'two parts, as shown,'or the engine can be caused to run idly without drivingthe car in either direction.

It will be noticed that the drivingsprocket and the sprocket chain are'arranged upon the outside of the car. This gives'the operator more roomto work in and avoids any liability of accident. Furthermore, this arrangement permits the linemen to stand up between the messenger wire and the sprocket chain.

What is claimed is':'

i In a device of the class described, the combination with supporting posts having cross arms thereon, ofbrackets depending from said cross arms, a cable connecting the brackets, a car, supporting arms pro ect1ng from the sides ofrthe car, shafts journaled in the upper ends of the arms, pulleys upon the inner ends of said shaft-s adapted to'en- 1 gage the cable, a motor arranged in the car and having a driving shaft projecting through the side thereof, and a connection between the driving shaft and shafts lying outside the car.
